It is also possible to change the various abrasives used to carry out the parts finishing through a tool change system.
The expertise obtained over the years has turned into highly accurate products. In fact, our turning department has technologically advanced machines with high performances, aimed at obtaining extreme flexibility, which allow us to meet a wide range of production requirements by working on both large and small materials, with N/C machines and centre lathes.
In particular, we have two N/C lathes with a stroke of up to 1000 mm and a maximum turning diameter of 380 mm; one of them has a bar loader, that allows us to automate and therefore speed up production processes. In addition, we have a lathe with a stroke of up to 2100 mm and a maximum turning diameter of 680 mm, two multitasking lathes with two spindles that can perform both turning and milling, with a stroke of up to 1000 mm and a maximum turning diameter of 660 mm.
A qualified staff checks all turning operations, promptly intervening in order to guarantee the best result of all the processing phases.
We carry out N/C milling work with both 3-axis and 5-axis machines to realize components requiring a high degree of precision. We perform 3-axis and 5-axis milling with high-speed and high-complexity machineries. We are equipped with the most modern machines to perform every type of milling; in particular, we have a vertical milling machine with x-axis stroke up to 3000 mm, and a vertical milling machine with tilting head and rotary table for 5-axis machining with x-axis stroke up to 3000 mm. The highly specialized staff and an experience of more than forty years acquired in very complex processes allow a rapid reply to the requests of the most demanding customers.
Among our machineries, machining centres undoubtedly play a key role: undisputed star of machine tools and modern mechanics. In order to meet the production requirements of large lots, we have machining centres equipped with multi-pallet systems, which are necessary to cope with milling operations even on large components. Our machining centres are technologically advanced with a very high flexibility, maximum precision and power: three factors typically required in our sectors, and which certainly contribute to increasing the productivity of our company. In particular, we have a 5-pallet horizontal machining centre with a rotating head and x-axis stroke up to 3100 mm, and a horizontal 2-pallet machining centre with a rotating head and x-axis stroke up to 3100 mm. Furthermore, we use powerful multifunctional machines with extremely qualifying technical peculiarities: high productivity, precision and reliability, all excellent features allowing us to achieve maximum performance and thus meet the needs of the highest standards required by our customers.

CMS constantly pursues total quality in all its processes and therefore the surface finishing plays a crucial role, because of the properties and features it confers to the product. CMS therefore makes use of a specific area for metals surface treatments. In fact, inside the production plant, within finishing department, specific tanks are available for pickling, passivation and electro-polishing. More precisely, we have two pickling tanks with dimensions up to 3000 mm x 1500 mm, two tanks for washing and degreasing parts with dimensions up to 3000 mm x 1500 mm, a passivation tank with dimensions up to 1500 mm x 1500 mm and a tank for electro-polishing with dimensions up to 1500 mm x 1500 mm.
These treatments are strictly important because they make products’ final surface completely decontaminated and uniform, as well as protected against atmospheric or corrosive agents.
We look for quality in all the phases of company processes, and in each of them, the attention to traceability has now become an essential element. Traceability begins with marking, so we have high quality laser markers for product identification through their numbering. In this way, we automate the identification procedures, ensuring a high level of control on our products. Taking advantage of specific focal lenses and a high laser power, essential factors for a precision marking, we are able to obtain optimal results and guarantee not only speed of execution but also maximum safety, thanks to an external cabin for fumes suction. We can make markings up to 200 mm x 200 mm, even on very large parts. Both simple numbers and even complex logos or drawings can be marked, depending on the Customer’s requests.
Constant and targeted investments in the most advanced technologies allow us to monitor the quality of all our products. In fact, CMS is equipped with an air-conditioned metrology room with constant pre-established thermal and hygrometric conditions in order to guarantee the maximum reliability in the execution of precise dimensional measurements. We have a complete range of measurement tools, necessary to assess the product’s conformity to the specifications of the assembly drawing: from specific measuring instruments – such as the roughness tester, the profilometer, the durometer, the altimeter – to the three-dimensional machines DEA and ZEISS used to verify dimensional and geometric tolerances, with automatic release of test report. We can measure parts of dimensions up to 3000 mm x 1500 mm. The operator programs the machines through specific three-dimensional models. In addition, we have a special software that allows the creation of the control program through self-learning.
